lax y United States Patent 3,388,881 DRAIN PIPE MOUNTING Leroy E. Anderson, Detroit Lakes, Minn., assignor to American Supply, Inc., Detroit Lakes, Minn., a corporation of Minnesota Filed Aug. 5, 1966, Ser. No. 570,540 13 Claims. (Cl. 248-44) ABSTRACT OF THE DISCLOSURE Disclosed herein is a drain pipe mounting formed from a single generally fiat rectangular plate which is U-shaped in form and has a base portion from which centrally disposed wall-engaging spacer elements are stricken inwardly and a pair of pipe grippers are struck outwardly from opposite sides of the base portion at each end of the spacer elements. A spring wire loop is pivotally connected to one end of the legs of the plate and is adapted to engage the other leg in pipe-clamping relation. The wire loop is characterized by a flat intermediate portion and outwardly curved terminal portions located outwardly of the vertical plane of the flat portion and deformable when tension is applied to the end of the loop to effectively hold the drain pipe against the gripper element of the plate.

The invention includes a U-shaped plate member adapted to receive and hold a drain pipe therewithin and having a base portion from which pipe-gripper elements are struck outwardly adjacent opposite ends thereof. As shown, these gripper elements extend normal to the base portion and horizontally and are vertically spaced with a pair at each end of the intermediate base portion. Also, the invention includes striking the intermediate side edges of the base portion inwardly to space the device from the wall at points intermediate the pipe-gripper elements. The invention includes a novel pipe-clamping member consisting of a loop of spring wire the intermediate portions of which extend generally in a single vertical plane and the terminal portions of which are bent outwardly and then inwardly again so that when tension is applied to the ends of the loop and they are secured to the ends of the legs of the plate, the deformation of the outwardly extending terminal portions effectively clamps the pipe against the pipe-gripper elements.

This invention relates to drain pipe mountings. More particularly, it relates to improved means for fixedly but readily and removably securing drain pipes to the walls of buildings in an improved manner.

It is the general object of my invention to provide a novel and improved drain pipe mounting of simple and inexpensive construction and application.

A still more specific object is to provide a novel and improved drain pipe mounting of simple and inexpensive construction and application by means of which the drain pipe may be easily and simply secured to the wall of the building in an improved manner and yet is capable of ready and simple detachment therefrom if desired.

Another object is to provide a novel and improved drain pipe mounting which will more positively grip the drain and hold the same against vertical slippage relative to the mounting in a more efiicient manner.

Another object is to provide a novel and improved drain pipe mounting which will facilitate the removal of the drain pipes in the event their removal is required or desired for construction, repair, or painting work thereunder or for the purpose of replacing the conductor pipe.

These and other objects and advantages of my invention will more fully appear from the following description, made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the several views, and in which:

FIG. 1 is a perspective view of the corner of a building with a vertically extending drain pipe mounted thereupon through the use of a pair of my drain pipe mountings.

FIG. 2 is a fragmentary side elevational view of one of my drain pipe mountings secured immediately below the lap on the siding, the wall of the building being shown fragmentarily in vertical section.

FIG. 3 is a perspective view of one of my drain pipe mountings before being secured to the Wall of a building;

FIG. 4 is a horizontal sectional view taken along line 4-4 of FIG. 2 and showing the mounting in secured position; and

FIG. 5 is a horizontal sectional view similar to that shown in FIG. 4 and illustrating the manner in which my drain pipe mounting is moved to drain pipe securing position.

The preferred embodiment of my invention is shown in FIGURES l5 inclusive. As shown, it is comprised of a single piece generally flat and rectangular plate member 6 which is U-shaped in form to adapt the same to receive a drain pipe 7 therewithin and in fixed relation thereto. As shown, the plate member 5 is formed from a single rectangular metal plate and a single piece of resilient spring wire 8 formed into a loop 9. Wherever hereinafter I have utilized the term single piece generally fiat and rectangular plate member which is U-shaped in form it is intended to connote that the U-shaped member has been formed from a single generally rectangular plate member so as to substantially reduce the cost of manufacture thereof. By examining FIG. 3 carefully, it can be readily seen that the plate member 6 has been formed from a single flat rectangular piece of metal which has been bent into U-shaped and has had portions thereof struck outwardly therefrom in opposite directions for purposes to be hereinafter described.

The plate member 6 which has been bent into a U- shaped form has a pair of generally parallel leg members 10 and 11 which extend outwardly from the opposite ends of the base portion 12. As shown, the base portion 12 is provided with a plurality of openings 13, 14, 15 to accommodate nails or screws 16 by means of which the plate member 6 may be secured to the wall 17 of a building. The base portion 12 has a pair of dogs 18 and 19 stricken outwardly at each of its opposite end portions to extend in a direction generally parallel to the fiat legs 16 and 11. These dogs 18 and 19 are drain pipe engaging and gripping elements which positively engage and secure a drain pipe such as the drain pipe 7 therewithin when the mounting has been clamped into position. At the intermediate area of the base portion 12 there is a pair of spacer elements 20, 21 which are stricken inwardly and in an opposite direction to the dogs 18, 19. These spacer elements 20, 21 extend parallel to each other and, as will be readily appreciated, are formed from the material which originally constituted a flat base portion connecting the two legs 10, 11.

The outer terminal portion of the leg 10 is formed into a pair of spaced sleeves 22, 23 which. as best shown in FIG. 3, receive and accommodate the otherwise free ends of the piece of wire from which the loop 8 has been formed. As shown, the ends of the wire have been formed into hinge elements 24, 25 to swingably mount the loop 8 upon the leg 10.

The loop 8 is formed from a single piece of resilient spring wire and has a pair of inwardly disposed intermediate portions 26 and 27 which connect more outwardly disposed curved sections 28, 29 and 30, 31. Thus, when viewed in a side elevation, the loop 8 has a pair of curved areas such as 29, 31 adjacent each of its ends and these curved areas arec-onnected by a flat intermediate area 27 3 which is disposed inwardly thereof to bear against the outer surface of the drain pipe 7. This can best be seen by reference to FIG. 4 and FIG. 5.

The free end of the leg member 11 is bent so as to extend normal to the length of the leg member and away i from the opposite leg member as best shown in FIG- URE 3 and FIGURE 4. The intermediate area of this terminal portion is cut away or relieved as at 32 to thereby form a pair of ears 33 and 34 with an intermedia-tely disposed fulcrum element 35 therebetween. The ears 33, 34 constitute engagement means for the loop or clamp 8 to secure the loop or clamp in tensioned position around the drain pipe 7 when the loop has been moved to the latching position shown in FIGURE 3 and FIGURE 4.

FIGURE 5 illustrates the manner in which the clamp 8 is moved into clamping position to positively secure the drain pipe 7 in fixed position relative thereto. As shown, the clamp 8 is swung into position such that the fiat intermediate portion 26 bears against the outer surface of the drain pipe 7. However, the curved areas 28, 29, and 30, 31 are of such length that the loop cannot be manually pressed over the ears 33, 34. To accomplish the secural of the clamp 8 in clamping position, a tool such as a screwdriver 36 is inserted as illustrated in FIG. 5 so that its point is within the end of the loop 8 and bears against the fulcrum 35 so that as the screwdriver is moved to the right as viewed in FIG. 5, the arcuate portions 28, 29 and 30, 31 will be tensioned and flattened as shown in FIG. 5 and the end of the loop 8 will be drawn outwardly over the ears 33 and 34 and will snap into engagement with the clamp engaging ears as shown in FIG. 3. Thus, the inherent resiliency of the loop 8 and particularly the arcuate portions 28, 29 and 30, 31 are under tension at all times and press the drain pipe 7 against the dogs 18, 19 at each end of the base portion 12 with substantial pressure such that these dogs tend to bite into the galvanized drain pipe 7 and positively hold the same against relative vertical movement even though the drain pipe may become filled with ice, dirt, water and the like. A single pair of my drain pipe mountings suchv as shown in FIG. 1 will fixed-1y secure the drain pipe despite such conditions.

When it is desired to remove the drain pipe 7 from my mounting, this can be accomplished by inserting the pointed end of a screwdriver or similar tool beneath the end portions of the loop which is secured by the ears 33 and 34 and twisting the screwdriver about its longitudinal axis to thereby cause the loop 8 to yield sufiiciently to slip over the cars 33 and 34 and thereby become free to swing outwardly to permit extraction or removal of the drain pipe 7.

From the above it can be seen that I have provided a novel and improved drain pipe mounting which is very inexpensive to manufacture in that it can be stamped from a single piece of flat metal and a single piece of spring wire. Moreover, it will be readily seen that the drain pipe 7 will be held in a much more secured relation to the mounting than by other mountings as heretofore known. The metal dogs 18, 19 have been found to perform in a highly improved manner as compared to other devices heretofore known for securing drain pipes to the Wall of a building. This makes these drain pipe mountings highly desirable particularly in view of the fact that the drain pipe can be so quickly and easily mounted within the mounting and can be quickly and easily removed therefrom if such is desired. Thus, if it becomes necessary to remove the drain pipe 7 in order to replace the same or to permit repair or construction work to the wall of the building there behind, the drain pipe 7 can be very quickly and easily removed and subsequently replaced with a minimum of effort and inconvenience.

It will also be noted that my new drain pipe mounting functions in an improved manner so as to at all times hold the drain pipe 7 free and clear of the wall of the building even though lapped siding may be utilized thereon. Refer ence to FIG. 2 shows how the spacer elements 20 and 21 hold the mounting plate 6 in spaced relation to the wall of the building and this feature plus the outward extension of the dog 18 and 19 cooperate to hold the drain pipe 7 in definitely spaced relation to the exterior surface of the building even though the mounting is applied to the wall of the building directly below the lap of the siding. Thus, if it is desired to paint the building, this operation can be accomplished without removal of the drain pipe if desired. Also, the wall of the building is free to dry quickly and easily after being painted. Moreover, the wall disposed immediately behind the drain pipe can dry very readily immediately after rainfall and consequent wetting of the wall therefrom.

It should be noted that the clamp or loop member 8 is primarily deformable about an axis transverse to its length and parallel to the length of the drain pipe held therewithin. Thus, when the arcuate portions 28, 29 and 30, 31 of the wire loop 8 are flattened as illustrated in FIG. 5, the deformity of the loop is primarily about an axis transverse to its length and parallel to the length of the pipe held therewithin since the deformity of the loop takes place as a result of the flattening of the curved portions of that member.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of this invention which consists of the matter shown and described herein and set forth in the appended claims.
